ABSTRACT:
In nonlinear optical crystal183D, each step of wavelength conversion can be performed using another fundamental wave that is output from light output unit1612, without using the fundamental wave whose output level has been attenuated after going through wavelength conversion for several steps (wavelength conversion in nonlinear optical crystals183A to183C). Therefore, the wavelength conversion efficiency improves and the peak power of optical amplifiers1611and1612can be suppressed, which allows the wavelength of lights that are output from optical amplifiers1611and1612to be further narrowed.
